#1562 closed defect (fixed)

Make reading version file more robust

Reported by: sayamindu Owned by: alsroot
Priority: Unspecified by Maintainer Milestone: Unspecified
Component: Sugar Version: Git as of bugdate
Severity: Unspecified Keywords: r?
Cc: Distribution/OS: OLPC
Bug Status: Unconfirmed

Description

If a filesystem corruption occurs just after the datastore has been written after first boot, on subsequent boots, Sugar refuses to start and the display-manager gets into an unending loop, making recovery without a reflash/re-install very difficult.

We can make the chances of this happening less by calling sync() after the datastore initialization, and also making the get_version() method more robust.

  • Summary changed from Ensure that datastore initialization is written completely to disk to Make reading version file more robust

In light of the discussion over at #1568, I decided to check if sync() in this particular case makes any difference, and it does not.
I think #1563 and the updated patch should deal with the problem.
